Watched the whole thing, I won't say that the two didn't do it, but based on the evidence presented in the trial, if i was a juror I don't think could state that the two did it without some reasonable doubts.
That said I do believe the Sheriff dept planted evidence, specifically the vehicle key, that was found by a detective who wasn't supposed to be there, that was missed in 6 (that's right Six) prior searches. Also the bullet found in the garage, how did they miss that the first time? Also, the tampering with the evidence seal on the vial of blood wasn't explained at all. I'm not saying the whole thing was a conspiracy on the sheriff's dept, but a lot of unanswered stuff.
Also where was the blood evidence of where she was killed, or any DNA evidence that she was assaulted, killed, dismembered on the property? The burnt bones? I think the defense made its case very well that they could have been placed there.
Anyway, worth watching, it will definitely make you scratch your head.
